1 Claims, 2 Drawing Figures 22 t rlIIIIII/I/l/l/ PATENTEU FEB 8 M72 INVENTOR DONALD H. BAGLEY ROBERT G. COOK ATTORNEY GLASS FIBER CORD RUBBER ROLLER BACKGROUND OF THE INVENTION 1. Field of the Invention The invention is directed to a tapered glass fiber core for a rubber roller.

2. Description of the prior Art U.S. Pat. No. 2,569,546 discloses the use of a rubber roller structure with glass fibers within the rubber structure.

U.S. Pat. No. 3,184,355 discloses a roll of structure which has a fiber inner core with a rubber coating thereover. The prior art to date has not used a phenolic glass fiber core as a substitute for a steel core on a rubber roller structure.

The particular roller structure herein is being utilized to move yarn. The yarn is grasped between two roller structures which rotate in opposite directions and drive the yarn in a single direction. To date, the particular roller structures have been made with rubber vulcanized to a steel core which was fastened to the drive shaft by the use of tapered sleeves at each end of the core. The tapered sleeves were generally conical in shape with the bases facing outward from the roller. As the two sleeves are drawn up between appropriate fastening structures, the two sleeves wedge against the ends of the roller structure and the drive shaft to hold the roller structure on the drive shaft. However, such a structure, when used in apparatus to drive yarn, suffered from a very high heat rise, and the steel core tended to expand excessively and become loose on the drive shaft.

It is an object of the particular glass fiber core of the structure herein to provide a highly thermally stable structure which will not be subject to noticeable expansion when the particular roller structure is utilized and to permit quick replacement of the sleeve at the operation without the need to strip and revulcanize on a new cover.

SUMMARY OF THE INVENTION The roller structure is meant to be used in a yarn driving apparatus wherein the yarn is caught between two coacting rollers and forced in a single direction. The roller sleeve is provided with a tapered core to facilitate its fastening onto the drive shaft. The conventional steel core structure has been replaced by a glass fiber phenolic resin structure which is extremely stable when subjected to heat. This glass fiber core thus provides a very stable mount for the rubber roller coating which is applied thereover. Also, the core is sufficiently stable that it maintains a good coaction with the drive shaft and does not become loose therefrom.

BRIEF DESCRIPTION OF THE DRAWING F I0. I is a view of the drive shaft and roller disassembled therefrom; and

FIG. II is an end view of two roller structures coacting to drive a piece ofyam.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring first to FIG. II, there are shown two roller structures 2 which are identical and coact together to drive the yarn 4 which is between the two rollers. As shown by the arrows 6 and 8, the rollers move in two opposite directions so that they will coact together to drive the yarn in a single direction which happens to be downward in the showing of FIG. II. The rollers are driven at approximately 278 r.p.m. for

a surface speed of 400 feet per minute. Appropriate structures force the two rollers toward each other in the directions indicated by arrows l0 and 12. The two rollers are forced together by a force of 500 pounds per inch of roll length. This particular structure is used in many cases with a 10 inch roll face and, consequently, a force of approximately 5,000 pounds is used to hold the two rolls in engagement with the yarn 4 which passes between the two rollers and is driven by the two rollers.

Referring now to FIG. I, there is shown a drive shaft structure 14 which is driven in a rotational pattern in the direction shown by arrow 16. The drive shaft is provided with a tapered body 18 at one end thereof. At the end of the tapered body 18 there is provided a threaded section 20. Since the drive element is fastened at only one end to an appropriate drive means, the particular drive structure will be referred to as a cantilever shaft drive.

The roller sleeve structure 22 is provided with a two-part core structure 24 and an outer rubber covering 26. The roller sleeve has a tapered core which coacts with the tapered body portion 18. A thrush washer 28 and a locknut 30 are used to hold the tapered core roller on the tapered shaft 18. The frictional fit between the core of the roller sleeve and the tapered drive shaft will permit the tapered shaft to drive the roller.

The core structure 24 of the roller sleeve is an inner layer 32 of a phenolic resin with a nitrile base. Over this is placed a coated glass fiber cord structure. This structure after curing forms a hardened core for the rubber coating. Over the cord is placed an adhesive and then the nitrile rubber compound which forms the outer rubber coating 26. The total roll of the structure is assembled and then placed in an oven and cured for 100 minutes at 315 F.

The inner layer 32 is formed as a sheet material which is wrapped around a form which gives the core its tapered shape. The composition of this layer 32 is a phenol-filled nitrile rubber which has 20 percent by weight of the phenol added to a conventional nitrile rubber binder. The layer which is formed of glass fiber is nothing more than a conventional Fiberglass" material which has been coated with a coating of nitrile rubber. The adhesive which is used to fasten the outer rubber compound to the inner core structure can be any solvent-type nitrile rubber phenolic resin which will be thermoset. Finally, the outer rubber coating is composed of a -90 Shore A durometer nitrile rubber formulation. Other nitrile rubber formulations could be used.

The inner core, which is now in effect a fiber glass core with a surrounding phenolic resin coating, provides a very thermally stable structure which is normally unaffected by the frictional heat encountered when this particular roller structure is used in an apparatus in the manner as shown in FIG. II. The heat which is generated by the drive of the yarn 4 against the roller coatings will still cause a rapid temperature buildup, but the fiber glass phenolic resin core will be unaffected by this. Consequently, the driven roller sleeve will now maintain its tight fit on the drive shaft.

We claim:

1. A two-layer roller sleeve structure which is provided with an inner first layer thermally stable core composed of a hardened layer made of only a phenolic resin wrapped with an outer layer of glass fiber strands, and over this an outer second layer of nitrile rubber, and wherein the hardened thermally stable core is of substantially uniform thickness and is provided with a tapered configuration.
